Build and Access times. A Time in hours spent building the binaries using 1 M to 150 M fragments. 'syst1' was a desktop pc (Dell Precision 390) with Windows Vista using a single CPU running at 2.4 GHz, 'syst2' was a single computational node (Xserve) with Mac OS X Server running at 2 GHz. B Time spent in seconds executing footprint queries using 100 to 250'000 unique locations spread uniformly across chromosomes. Each point correspond to the average over 10 different replicates, the black line indicate maximum and minimum value for the replicates.
